at the end of the day, it depends on the priority of the trader what to use in terms of trading platforms.
I agree with you, because centralized exchanges offer extra features that may be interesting for traders and investors, such as staking and investment programs for altcoins and bitcoin, plus debit/credit cards, completely replacing the function of banks in someone's life. The fact they exist as a regulated business also means an extra security layer for customers, as this business can't just scam everyone without consequences for the managers behind the company. Both kinds of exchanges, centralized and decentralized ones, have positive and negative aspects which should be taken in consideration in a case by case basis. Something good for me, might not be good for you, so individual discernment is a must.
